2K resolution is a generic term for display devices or content having a horizontal resolution of approximately 2,000 pixels.[1] In the movie projection industry, Digital Cinema Initiatives is the dominant standard for 2K output and defines a 2K format with a resolution of Шаблон:Resx.[2][3] For television and consumer media, Шаблон:Resx is the most common 2K resolution, but this is normally referred to as 1080p.

Standards and terminology

In the cinematography industry, 2K resolution traditionally refers to a digital scan of 35Шаблон:Nbspmm film with a resolution around 2000 pixels wide. Typically this is done at Шаблон:Resx, but the exact dimensions vary based on the aspect ratio and size of the scan area.[4]Шаблон:Rp

Another common 2K resolution in cinema is Шаблон:Resx. This is the resolution of the 2K container format standardized by DCI in their Digital Cinema System Specification in 2005.[2][3] The resolution of the encapsulated video content follows the SMPTE 428-1 standard,[5]Шаблон:Rp which establishes the following resolutions for a 2K distribution:[6]Шаблон:Rp

However, the term 2K itself is generic, was not coined by DCI, and does not refer specifically to the DCI 2K standard. Usage of the term 2K predates the publication of the DCI standard.[7][8][9]

The resolution Шаблон:Resx has also been referred to as a 2K resolution by other standards organizations like NHK Science & Technology Research Laboratories and ITU Radiocommunication Sector (which were involved in the standardization of 1080p HDTV and 4K UHDTV).[10][11]
